Recommendations

Run all software as a nonprivileged user with minimal access rights.

To reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged user with minimal access rights.

Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This includes but is not limited to
requests that include NOP sleds and unexplained incoming and outgoing traffic. This may indicate exploit attempts or
activity that results from successful exploits

Do not follow links provided by unknown or untrusted sources.

Web users should be cautious about following links to sites that are provided by unfamiliar or suspicious sources.
Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.
